Solar power

In the manufacture of portable solar-powered chargers, one problem always arises: a small solar battery cannot generate large currents, which means a rather slow

This charger for finger batteries is distinguished by its unusual simplicity and ease of assembly. It is based on the use of solar panels, due to which there is a charge

In a previous article, we already talked about how to make a USB charger on a solar battery. However, that design has one significant drawback: charging can only be done in

The author came up with the idea to create a charger for his phone based on a solar battery. Typically, charging a mobile phone requires a constant voltage of 5 V. Voltage

In past articles, we have already seen examples of mobile power plants. In their purpose, application and essence of the work, they are not very different, their main difference lies in one very important

In this project, the author decided to make a solar collector for heating the pool. Since the roof of the buildings heats up quite strongly in the summer, the author decided to use this factor as an element

The most popular ways to use solar energy to heat water is to create flat or vacuum solar collectors. However, there are still methods with a rather high coefficient of efficiency,

It is difficult to overestimate the advantages of a mobile solar power station. Such a thing will always be your backup power source for your home power system, but you can also take it with you to those

To make this solar panel, the author needed 36 polycrystalline solar cells. The size of the elements is 3 by 6 inches. Since each element separately produces voltage

If you decide to assemble a solar panel on your own, then you are likely to come across such a thing as soldering conductors to solar cells. The process of soldering tires to solar cells per se

Here is an example of an excellent portable power station, which has the following characteristics: built-in battery, the ability to connect an external battery, the ability to charge them from

When it is hot outside, the amount of such garbage as plastic bottles increases significantly in the world. These are bottles from mineral water, from juices, beer and much more. One author suggested

Many of those who use an electric boiler in a private house sooner or later encounter a problem when the boiler starts to leak. But the worst thing about this is that the boiler is pretty heavy

There are many examples of how to make a solar collector. The most important thing is to understand its working principle, and it is very simple. The sun actively heats black metals and to make
